Some Applications of the High-mode-merging Method

Waves guided along dielectric step discontinuity can be described by a multi-port network [1] and it is simplified as a two-port network with the influence of high-modes retaining [2]. These results can be used for treat dielectric strip waveguide, even more complicated structures. Some numerical results are got for a strip and a groove dielectric waveguide some kind of resonant phenomena also is obtained. Some comments on this method and some suggestions are given furthermore.
